Leading CAD Programs Demonstrate Integration in Frankfurt

San Francisco, December 31, 1997

In support of the International Alliance for Interoperability's (IAI) initiative to
establish a universal CAD file standard, Graphisoft announces it will integrate
IAI's Industry Foundation Classes (IFC) into coming releases of ARCHICAD in
1998. Using IFC files, ARCHICAD will facilitate high level object-oriented communication with other
software and building products manufacturers.

In a demonstration at the ACS Show held November 12 - 14 in Frankfurt, Germany, Graphisoft and other
leading CAD manufacturers demonstrated seamless file sharing using the IAI's Industry Foundation Classes
(IFC) file format. The select group of CAD software developers gave a live
demonstration in which they collaborated to create a building by passing
a single 3D model containing rooms, windows, doors, columns and site
data as intelligent objects.

"Intelligent objects are deeply routed in our company history and philosophy," says Tamás Hajas,
Graphisoft R&D's vice president of development. "It is only natural that, as a leading developer of
object-oriented technology, we incorporate the work of the International Alliance for Interoperability into
ArchiCAD."

A member of the IAI since 1996, Graphisoft is committed to developing its own IFC version 1.5
ARCHICAD-toolbox. The IFC file format will provide architects with a bridge between software programs
and building products manufacturers. IFC describes not only the physical dimensions of a given object, but
stores information about its composition and assembly and descriptive data as well. IFC can facilitate
bidirectional communication between CAD software and CAM, project scheduling, and facilities
management applications.
